FIELD OF THE INVENTION

The present disclosure relates generally to the fields of gene therapyand immunotherapy, specifically in relation to increased activation ofgamma delta (“GD”) T cells.

BACKGROUND

Human T cells are distinguished on the basis of T cell receptorstructure. The major populations, including CD4+ and CD8+ subsets,express a receptor composed of alpha and beta chains. A smaller subsetexpresses T cell receptor made from gamma and delta chains. Gamma delta(“GD”) T cells make up 3-10% circulating lymphocytes, and Vδ2+ subsetmakes up 75% of GD T cells in blood. Vδ2+ cells recognize non-peptideepitopes and do not require antigen presentation by majorhistocompatibility complexes (“MHC”) or human leukocyte antigen (“HLA”).The majority of Vδ2+ T cells also express a Vγ9 chain and are stimulatedby exposure to 5-carbon pyrophosphate compounds that are intermediatesin mevalonate and non-mevalonate sterol/isoprenoid synthesis pathways.The response to isopentenyl pyrophosphate (5-carbon) is universal amonghealthy human beings.

Another subset of GD T cells, Vδ1+, make up a much smaller percentage ofthe T cells circulating in the blood, but Vδ+1 cells are commonly foundin the epithelial mucosa and the skin.

In general, GD T cells have several functions, including killing tumorcells and pathogen-infected cells. Stimulation through their unique Tcell receptor (“TCRs”) composed of two glycoprotein chains, γ and δ,improves the capacity for cellular cytotoxicity, cytokine secretion andother effector functions. The TCRs of GD T cells have uniquespecificities and the cells themselves occur in high clonal frequencies,thus allowing rapid innate-like responses to tumors and pathogens.

Aminobisphosphonate drugs (“ABPs”) and other inhibitors of farnesyldiphosphate synthase (“FDPS”), which are downstream from isopentenylpyrophosphate (“IPP”) in the mevalonate pathway (see, for e.g., FIG. 1),have been used to treat various diseases, including cancers,specifically those involving bone metastasis. ABPs include trade namessuch as Zometa® (Novartis) and Fosamax® (Merck).

ABPs have also been used to stimulate GD T cells. This may be becausewhen FDPS is inhibited in myeloid cells, IPP begins to accumulate andgeranylgeranyl pyrophosphate (“GGPP”), a downstream product of FDPS thatsuppresses activation of the inflammasome pathway, is reduced. Thereduction in GGPP removes an inhibitor of the caspase-dependentinflammasome pathway and allows secretion of mature cytokines includinginterleukin-beta and interleukin-18, the latter being especiallyimportant for gamma delta T cell activation.

Thus, when FDPS is blocked, the increased IPP and decreased GGPP combineto activate Vδ2+ T cells. Vδ2+ cells activated by IPP or ABPs willproliferate rapidly, express a number of cytokines and chemokines, andcan function to cytotoxically destroy tumor cells or cells infected withpathogenic microorganisms.

However, ABPs are associated with inflammation and osteonecrosis, aswell as having poor bioavailability due to their chemistry. Likewise,IPP has a very short half-life and is difficult to synthesize. Bothtypes of compounds require systemic administration in an individual.Accordingly, both ABPs in general, and IPP specifically, leave a greatdeal to be desired for therapeutic purposes.

Depending on the application, the“percent identity” can exist over a region of the sequence beingcompared, e.g., over a functional domain, or, alternatively, exist overthe full length of the two sequences to be compared. For sequencecomparison, typically one sequence acts as a reference sequence to whichtest sequences are compared. When using a sequence comparison algorithm,test and reference sequences are input into a computer, subsequencecoordinates are designated, if necessary, and sequence algorithm programparameters are designated. The sequence comparison algorithm thencalculates the percent sequence identity for the test sequence(s)relative to the reference sequence, based on the designated programparameters.

Optimal alignment of sequences for comparison can be conducted, e.g., bythe local homology algorithm of Smith & Waterman, Adv. Appl. Math. 2:482(1981), by the homology alignment algorithm of Needleman & Wunsch, J.Mol. Biol. 48:443 (1970), by the search for similarity method of Pearson& Lipman, Proc. Nat'l. Acad. Sci. USA 85:2444 (1988), by computerizedimplementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA inthe Wisconsin Genetics Software Package, Genetics Computer Group, 575Science Dr., Madison, Wis.), or by visual inspection (see generallyAusubel et al., infra).

One example of an algorithm that is suitable for determining percentsequence identity and sequence similarity is the BLAST algorithm, whichis described in Altschul et al., J. Mol. Biol. 215:403-410 (1990).Software for performing BLAST analyses is publicly available through theNational Center for Biotechnology Information website.

The percent identity between two nucleotide sequences can be determinedusing the GAP program in the GCG software package (available athttp://www.gcg.com), using a NWSgapdna.CMP matrix and a gap weight of40, 50, 60, 70, or 80 and a length weight of 1, 2, 3, 4, 5, or 6. Thepercent identity between two nucleotide or amino acid sequences can alsobe determined using the algorithm of E. Meyers and W. Miller (CABIOS,4:11-17 (1989)) which has been incorporated into the ALIGN program(version 2.0), using a PAM120 weight residue table, a gap length penaltyof 12 and a gap penalty of 4. In addition, the percent identity betweentwo amino acid sequences can be determined using the Needleman andWunsch (I Mol. Biol. (48):444-453 (1970)) algorithm which has beenincorporated into the GAP program in the GCG software package (availableat http://www.gcg.com), using either a Blossum 62 matrix or a PAM250matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a lengthweight of 1, 2, 3, 4, 5, or 6.

The nucleic acid and protein sequences of the present disclosure canfurther be used as a “query sequence” to perform a search against publicdatabases to, for example, identify related sequences. Such searches canbe performed using the NBLAST and) (BLAST programs (version 2.0) ofAltschul, et al. (1990) J. Mol. Biol. 215:403-10. BLAST nucleotidesearches can be performed with the NBLAST program, score=100, wordlength=12 to obtain nucleotide sequences homologous to the nucleic acidmolecules provided in the disclosure. BLAST protein searches can beperformed with the XBLAST program, score=50, wordlength=3 to obtainamino acid sequences homologous to the protein molecules of thedisclosure. To obtain gapped alignments for comparison purposes, GappedBLAST can be utilized as described in Altschul et al., (1997) NucleicAcids Res. 25(17):3389-3402. When utilizing BLAST and Gapped BLASTprograms, the default parameters of the respective programs (e.g.,XBLAST and NBLAST) can be used. See http://www.ncbi.nlm.nih. gov.

Methods of GD T Cell Activation

Provided herein are compositions and methods for activating GD T cellsin an individual, as well as methods for treating tumors and infectiousdiseases. For instance, in embodiments, the compositions and methodsprovided herein can be used in methods to treat all known cancersbecause activated GD T cells comprise a natural mechanism for immunesurveillance of tumors (See for e.g.: Pauza et al. 2014 Frontiers inImmunol. 5:687). Likewise, in embodiments, the compositions and methodsprovided herein can be used to treat infectious diseases, including butnot limited to flavivirus, influenza virus, human retrovirus,mycobacteria, plasmodia and a variety of other viral, fungal andbacterial infections. (See for e.g.: Pauza and Cairo, 2015 Cell Immunol.296(1).

In general, a vector system is administered to an individual totransfect or transduce a target cell population with the disclosedconstructs for decreasing expression of FDPS and, in other embodiments,increasing expression of chemokines or cytokines. Administration andtransfection/transduction can occur in vivo or ex vivo, with thetransfected cells later administered back into the subject in the latterscenario.

Administration of the disclosed vectors and transfection or transductionof the disclosed constructs into a subject's cells result in decreasedexpression of FDPS, increased expression of cytokines or chemokines,accumulation of IPP and in many cases, reduced growth rates forgenetically modified tumor cells. All of these features work together toactivate and co-localize GD T cells to the site of a tumor or infection.

The disclosed methods can also increase the capacity of NK cells torecognize and destroy tumor cells and/or infected cells. Crosstalkbetween GD T cells and NK cells is an important aspect of regulating theimmune and inflammatory responses. Further, GD T cells are known totrigger dendritic cell maturation, recruit B cells and macrophages, andparticipate in a variety of cytolytic activities, such as secretion ofinterferon-γ and TNF-α.

In embodiments, the disclosed compositions and methods provided hereincomprise a form of gene therapy for activating GD T cells at the site oftumor or infectious disease pathology. In an aspect, the compositionsand methods provided herein activate GD T cells and support theirproliferation, differentiation, and functional capacities by promotingthe production of specific cytokines needed for cytolytic activitycapable of killing cancer cells or treating infectious diseases.

In embodiments the gene therapy sequences (e.g., FDPS shRNAs) arecarried by therapeutic vectors, including but not limited to viralvectors such as lentiviruses or adeno-associated viruses, although otherviral vectors can also be suitable. Gene therapy constructs may also bedelivered in the form of DNA or RNA, including but not limited toplasmid forms. In embodiments, the disclosed gene therapy constructs mayalso be delivered in the form of protein-nucleic acid complexes or lipidnucleic acid complexes and mixtures of these formulations. For instance,a protein-nucleic acid complex can comprise nucleic acids of interest ina complex with cationic peptides such as lysine and arginine.Lipid-nucleic acids complexes can comprise lipid emulsions, micelles,liposomes, and/or mixtures of neutral and cationic lipids such as DOTMA,DOSPA, DOTAP, and DMRIE.

In embodiments, therapeutic vectors may comprise a single construct orat least two, at least three, at least four, or at least five differentconstructs. When more than one construct is present in a vector theconstructs may be identical, or they may be different. For instance, theconstructs may vary in terms of their promoters, the presence or absenceof an integrating elements, and/or their sequences. In some embodiments,a therapeutic vector will comprise at least one construct that encodes asmall RNA capable of knocking down the expression of FDPS. Inembodiments, the therapeutic vector will also encode a specificcytokine(s) and/or chemokine(s), including but not limited to TNF-α,interferon-γ, IL-1, IL-2, IL-15, IL-17, IL-18 or IL-12. In someembodiments, a single construct may encode both small RNAs capable ofknocking down the expression of FDPS and specific cytokines orchemokines, including but not limited to TNF-α, interferon-γ, IL-1,IL-2, IL-15, IL-17, IL-18 or IL-12.

In embodiments, viral vectors may introduce nucleic acid constructs thatbecome integrated into the host chromosome. Alternately, transientdelivery vectors may be used to prevent chromosomal integration andlimit the lifespan of gene therapy constructs.

In embodiments, the disclosed constructs and vectors comprise shorthomology region RNA (“shRNA”), micro RNA (“miRNA”), or siRNA capable ofreducing or knocking down expression of FDPS and/or geranylpyrophosphate synthase (“GPPS”) and/or farnesyl transferase (“FT”)genes. By down regulating these genes, which control steroid andisoprenoid synthesis, isopentenyl pyrophosphate (“IPP”) levels areelevated. Elevation and accumulation of IPP is a known mechanism forincreasing GD T cells activation. Further, down regulation of thesepyrophosphate synthase genes removes an important negative regulator ofinflammasome function that in turn results in increased expression ofcytokines that are important for GD T cell activation and effector cellfunction.

In embodiments, the disclosed constructs are regulated by specificpromoters that are capable of producing interleukin-2 and/orinterleukin-15 to sustain GD T cell proliferation. In addition, thedisclosed constructs may be regulated by specific promoters that arecapable of producing interleukin-1 beta and/or interleukin-18 and/orinterferon-gamma required for GD T cell differentiation and acquisitionof all effector cell function. Desirable effector cell functions includethe capacity for direct cytotoxic cell killing of tumors and/or infectedcells, secretion of beneficial cytokines and/or chemokines, increasedexpression of NK receptors required to recognize cancerous or infectedcells, and increased expression of Fc receptors needed to bind targetingantibodies in order to co-localize GD T cells with cancerous or infectedcell targets.

In embodiments, the disclosed methods activate GD T cells, resulting inthe indirect effect of increasing the capacity for NK cells to attackand destroy cancerous cells, tumors, or infected cells. The activationof NK cells requires GD T cells that are stimulated to proliferate anddifferentiate, and to express 4-1BBL costimulatory ligand needed toengage the 4-1BB costimulatory receptor on NK cells. This form ofcrosstalk is known as an important mechanism for activating NK cells andis achieved here through the action of the disclosed methods andcompositions.

In another aspect, crosstalk between GD T cells and NK cells is animportant mechanism for eliminating inflammatory dendritic cells thataccumulate in diseased tissues. Alone, neither GD T cells nor NK cellsare capable of destroying dendritic cells, but once the aforementionedcrosstalk interactions have occurred, NK cells are altered to becomecytotoxic against inflammatory dendritic cells. This immuno-regulatorymechanism depends on strong activation and proliferation of GD T cells.

In embodiments, the disclosed methods for activation of GD T cellsfurther comprise a step of suppressing pathologic inflammatory responsesthat may include cellular proliferation leading to atherosclerosis,chronic immune activation that stimulates tumor growth, autoimmunediseases including psoriasis and other presentations in the epidermis,inflammatory diseases of the central nervous system, and arthritis andother diseases of unregulated immune responses.

In embodiments, therapeutic vectors are administered concurrently withaminobisphosphonate (ABP) drugs to achieve synergistic activation ofgamma delta T cells. The synergism can allow alternate, modified orreduced doses of ABP and may decrease adverse reactions to ABP includingacute inflammatory responses and chronic diseases.

Constructs for GD T Cell Activation

Inhibition of FDPS results in IPP accumulation, resulting in activationof Vδ2+ GD T cells and expression of IL-18, which is also important inactivating GD T cells. Inhibition of farnesyl transferase results indecreased prenylation of proteins. The disclosed constructs can betransfected or transduced into specific target cells, like tumor cellsor infected cells, where they can express RNA sequences (i.e., siRNA,shRNA or microRNA) that will inhibit translation of FDPS as well asencode and express cytotoxic cytokines or chemokines.

Disclosed herein are constructs for decreasing expression of FDPS and/orFT, increasing expression of cytokines, and increasing expression ofchemokines including RANTES. For instance, in some embodiments theconstructs may encode for interferon-gamma, IL-1, IL-2, IL-15, IL-17,IL-18 or IL-12.

Expression of cytokines and chemokines, like those listed above, willresult in localized cytotoxic destruction of tumor cells or cellsinfected with pathogenic organisms. Accordingly, expression of suchconstructs by a tumor cell or an infected cell will result in theunwanted cells assisting in its own destruction.

Likewise, if the disclosed constructs are expressed in a tumor cell orinfected cell, decreasing the expression of FDPS and FT will result inactivation and recruitment of GD T cells to the tumor site of site ofcell infection. Increasing expression of RANTES will further attract GDT cells to intended tissue location. Because GD T cells can kill a broadrange of tumors of epithelial origin as well as many leukemias andlymphomas, and are further able to produce high levels of the anti-tumorcytokine, IFNγ, recruitment of GD T cells to the site of a tumor can bea particularly effective means of inducing anti-tumor immunity.

Decreased expression of FDPS can be achieved via shRNA, microRNA, siRNA,or other means known in the art. For instance, shRNAs according to SEQID NOS: 1, 2, 3, or 4, or variants thereof can be used in the disclosedconstructs and methods, although this example is not limiting. Thecoding regions for RNAs to decrease expression of FDPS and FT and thecoding regions of cytokine and chemokines may be in the same constructor on different constructs.

The classical approach for the production of recombinant polypeptides orgene regulatory molecules including small RNA is the use of stableexpression constructs. These constructs are based upon chromosomalintegration of a transduced expression plasmid (or at least a portionthereof) into the genome of the host cell, short-duration plasmidtransfection, or non-integrating viral vectors also with limitedhalf-life. The sites of gene integration are generally random, and thenumber and ratio of genes integrating at any particular site are oftenunpredictable; likewise, non-integrating plasmids or viral vectors alsogenerate nuclear DNA but these species usually lack sequences requiredfor DNA replication and continuous maintenance. Thus, constructs thatrely on chromosomal integration result in permanent maintenance of therecombinant gene that may exceed the therapeutic interval.

An alternative to stable expression constructs for gene expression aretransient expression constructs. The expression of the latter geneexpression construct is based on non-integrated plasmids, and hence theexpression is typically lost as the cell undergoes division or theplasmid vectors are destroyed by endogenous nucleases.

The disclosed constructs are preferably episomal constructs that aretransiently expressed. Episomal constructs are degraded or diluted overtime such that they do not make permanent changes to a subject's genome,nor are they incorporated into the chromosome of a target cell. Theprocess of episomal replication typically incorporates both host cellreplication machinery and viral trans-acting factors.

Avoiding chromosomal integration reduces certain barriers to in vivogene delivery. However, even integration-defective constructs can have abackground frequency of integration, and any DNA molecule can find rarehomologies to recombine with host sequences; but these rates ofintegration are exceptionally rare and generally not clinicallysignificant.

Thus, in some embodiments, the disclosed vectors support active geneand/or small RNA delivery over a period of about 1, about 2, about 3,about 4, about 5, about 6, about 7, about 8, about 9, about 10, about11, or about 12 weeks. In some embodiments, the disclosed vectorssupport active gene and/or small RNA delivery over a period of about 1month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8months, 9 months, 10 months, 11 months, 12 months, or longer. Anycombination of these time periods can also be used in the methods of theinvention, e.g., 1 month and 1 week, or 3 months and 2 weeks.

However, in some embodiments, the constructs comprise integratingelements that depend on a retroviral integrase gene, such that theconstruct becomes integrated into the subject's chromosome.Retrotransposition and transposition are additional examples ofmechanisms whereby mobile genetic elements become integrated or insertedinto the chromosome. Plasmids may become integrated into the chromosomeby recombination, and gene editing technologies including CRISPR andTALEN utilize guide RNA sequences and alter chromosomal loci by geneconversion mechanisms.

Constructs may comprise specific promoters for expressing cytokinesinvolved in the maintenance of GD T cells (i.e. IL-2, IL-7, IL-17, andIL-15). For example, promoters that may be incorporated into thedisclosed constructs include but are not limited to TATA-box promoters,CpG-box promoters, CCAAT-box promoters, TTGACA-box promoters, BRE-boxpromoters, INR-box promoters, AT-based promoters, CG-based promoters,ATCG-compact promoters, ATCG-balanced promoters, ATCG-middle promoters,ATCG-less promoters, AT-less promoters, CG-less promoters, AT-spikepromoters, and CG-spike promoters. See Gagniuc and Ionescu-Tirgoviste,Eukaryotic genomes may exhibit up to 10 generic classes of genepromoters, BMC GENOMICS 13:512 (2012).

Therapeutic Vectors

The construct can be delivered via known transfection and/ortransduction vectors, including but not limited to lentiviral vectors,adeno-associated virus, poxvirus, herpesvirus vectors, protein and/orlipid complexes, liposomes, micelles, and the like.

Viral vectors can be preferentially targeted to cell types that areuseful for the disclosed methods (i.e., tumor cells or myeloid cells).Viral vectors can be used to transduce genes into target cells owing tospecific virus envelope-host cell receptor interactions and viralmechanisms for gene expression. As a result, viral vectors have beenused as vehicles for the transfer of genes into many different celltypes including whole embryos, fertilized eggs, isolated tissue samples,tissue targets in situ, and cultured cell lines. The ability tointroduce and express foreign genes in a cell is useful for the study ofgene expression, and the elucidation of cell lineages as well asproviding the potential for therapeutic interventions such as genetherapy, somatic cell reprogramming of induced pluripotent stem cells,and various types of immunotherapy. Viral components from viruses likePapovaviridae (e.g. bovine papillomavirus or BPV) or Herpesviridae (e.g.Epstein Barr Virus or EBV) or Hepadnaviridae (e.g. Hepatitis B Virus orHBV) or pox vectors including vaccinia may be used in the disclosedvectors.

Lentiviral vectors are a preferred type of vector for the disclosedcompositions and methods, although the disclosure is not specificallylimited to lentiviral vectors. Lentivirus is a genus of viruses that candeliver a significant amount of viral nucleic acid into a host cell.Lentiviruses are characterized as having a unique ability toinfect/transduce non-dividing cells, and following transduction,lentiviruses integrate their nucleic acid into the host cell'schromosomes.

Infectious lentiviruses have three main genes coding for the virulenceproteins gag, pol, and env, and two regulatory genes including tat andrev. Depending on the specific serotype and virus, there may beadditional accessory genes that code for proteins involved inregulation, synthesis, and/or processing viral nucleic acids and otherreplicative functions.

Moreover, lentiviruses contain long terminal repeat (LTR) regions, whichmay be approximately 600 nt long. LTRs may be segmented into U3, R, andU5 regions. LTRs can mediate integration of retroviral DNA into the hostchromosome via the action of integrase. Alternatively, withoutfunctioning integrase, the LTRs may be used to circularize the viralnucleic acid.

Viral proteins involved in early stages of lentivirus replicationinclude reverse transcriptase and integrase. Reverse transcriptase isthe virally encoded, RNA-dependent DNA polymerase. The enzyme uses aviral RNA genome as a template for the synthesis of a complementary DNAcopy. Reverse transcriptase also has RNaseH activity for destruction ofthe RNA-template. Integrase binds both the viral cDNA generated byreverse transcriptase and the host DNA. Integrase processes the LTRbefore inserting the viral genome into the host DNA. Tat acts as atrans-activator during transcription to enhance initiation andelongation. The rev responsive element acts post-transcriptionally,regulating mRNA splicing and transport to the cytoplasm.

Viral vectors, in general, comprise glycoproteins and the variousglycoproteins may provide specific affinities. For instance, VSVGpeptides can increase transfection into myeloid cells. Alternatively,viral vectors can also have targeting moieties, such as antibodies,attached to their shell peptides. Targeting antibodies can be specificfor antigens that are overexpressed on a tumor, for instance, likeHER-2, PSA, CEA, M2-PK, and CA19-9.

Other viral vector specificities are also known in the art and can beused to target particular populations of cells. For example, poxvirusvectors target to macrophages and dendritic cells.

Lentiviral Vector System

A lentiviral virion (particle) is expressed by a vector system encodingthe necessary viral proteins to produce a virion (viral particle). Thereis at least one vector containing a nucleic acid sequence encoding thelentiviral pol proteins necessary for reverse transcription andintegration, operably linked to a promoter. In another embodiment, thepol proteins are expressed by multiple vectors. There is also a vectorcontaining a nucleic acid sequence encoding the lentiviral gag proteinsnecessary for forming a viral capsid operably linked to a promoter. Inan embodiment, this gag nucleic acid sequence is on a separate vectorthan at least some of the pol nucleic acid sequence. In anotherembodiment, the gag nucleic acid is on a separate vector from all thepol nucleic acid sequences that encode pol proteins.

Numerous modifications can be made to the vectors, which are used tocreate the particles to further minimize the chance of obtaining wildtype revertants. These include, but are not limited to deletions of theU3 region of the LTR, tat deletions and matrix (MA) deletions.

The gag, pol and env vector(s) do not contain nucleotides from thelentiviral genome that package lentiviral RNA, referred to as thelentiviral packaging sequence.

The vector(s) forming the particle preferably do not contain a nucleicacid sequence from the lentiviral genome that expresses an envelopeprotein. Preferably, a separate vector that contains a nucleic acidsequence encoding an envelope protein operably linked to a promoter isused. This env vector also does not contain a lentiviral packagingsequence. In one embodiment the env nucleic acid sequence encodes alentiviral envelope protein.

In another embodiment the envelope protein is not from the lentivirus,but from a different virus. The resultant particle is referred to as apseudotyped particle. By appropriate selection of envelopes one can“infect” virtually any cell. For example, one can use an env gene thatencodes an envelope protein that targets an endocytic compartment suchas that of the influenza virus, VSV-G, alpha viruses (Semliki forestvirus, Sindbis virus), arenaviruses (lymphocytic choriomeningitisvirus), flaviviruses (tick-borne encephalitis virus, Dengue virus,hepatitis C virus, GB virus), rhabdoviruses (vesicular stomatitis virus,rabies virus), paramyxoviruses (mumps or measles) and orthomyxoviruses(influenza virus). Other envelopes that can preferably be used includethose from Moloney Leukemia Virus such as MLV-E, MLV-A and GALV. Theselatter envelopes are particularly preferred where the host cell is aprimary cell. Other envelope proteins can be selected depending upon thedesired host cell. For example, targeting specific receptors such as adopamine receptor can be used for brain delivery. Another target can bevascular endothelium. These cells can be targeted using a filovirusenvelope. For example, the GP of Ebola, which by post-transcriptionalmodification become the GP, and GP2 glycoproteins. In anotherembodiment, one can use different lentiviral capsids with a pseudotypedenvelope (for example, FIV or SHIV [U.S. Pat. No. 5,654,195]). A SHIVpseudotyped vector can readily be used in animal models such as monkeys.

As detailed herein, a lentiviral vector system typically includes atleast one helper plasmid comprising at least one of a gag, pol, or revgene. Each of the gag, pol and rev genes may be provided on individualplasmids, or one or more genes may be provided together on the sameplasmid. In one embodiment, the gag, pol, and rev genes are provided onthe same plasmid (e.g., FIG. 2). In another embodiment, the gag and polgenes are provided on a first plasmid and the rev gene is provided on asecond plasmid (e.g., FIG. 3). Accordingly, both 3-vector and 4-vectorsystems can be used to produce a lentivirus as described in the Examplessection and elsewhere herein. The therapeutic vector, the envelopeplasmid and at least one helper plasmid are transfected into a packagingcell line. A non-limiting example of a packaging cell line is the293T/17 HEK cell line. When the therapeutic vector, the envelopeplasmid, and at least one helper plasmid are transfected into thepackaging cell line, a lentiviral particle is ultimately produced.

In another aspect, a lentiviral vector system for expressing alentiviral particle is disclosed.

In another aspect,sequence variation, by way of substitution, deletion, addition, ormutation can be used to modify the sequences references herein.

In another aspect, the plasmids used for lentiviral packaging can bemodified with similar elements and the intron sequences couldpotentially be removed without loss of vector function. For example, thefollowing elements can replace similar elements in the plasmids thatcomprise the packaging system: Elongation Factor-1 (EF-1),phosphoglycerate kinase (PGK), and ubiquitin C (UbC) promoters canreplace the CMV or CAG promoter. SV40 poly A and bGH poly A can replacethe rabbit beta globin poly A. The HIV sequences in the helper plasmidcan be constructed from different HIV strains or clades. The VSV-Gglycoprotein can be substituted with membrane glycoproteins from felineendogenous virus (RD114), gibbon ape leukemia virus (GALV), Rabies(FUG), lymphocytic choriomeningitis virus (LCMV), influenza A fowlplague virus (FPV), Ross River alphavirus (RRV), murine leukemia virus10A1 (MLV), or Ebola virus (EboV).

Of note, lentiviral packaging systems can be acquired commercially(e.g., Lenti-vpak packaging kit from OriGene Technologies, Inc.,Rockville, Md.), and can also be designed as described herein. Moreover,it is within the skill of a person skilled in the art to substitute ormodify aspects of a lentiviral packaging system to improve any number ofrelevant factors, including the production efficiency of a lentiviralparticle.

EXAMPLES Example 1 Development of a Lentiviral Vector System

A lentiviral vector system was developed as summarized in FIG. 4(circularized form). Lentiviral particles were produced in 293T/17 HEKcells (purchased from American Type Culture Collection, Manassas, Va.)following transfection with the therapeutic vector, the envelopeplasmid, and the helper plasmid. The transfection of 293T/17 HEK cells,which produced functional viral particles, employed the reagentPoly(ethylenimine) (PEI) to increase the efficiency of plasmid DNAuptake. The plasmids and DNA were initially added separately in culturemedium without serum in a ratio of 3:1 (mass ratio of PEI to DNA). After2-3 days, cell medium was collected and lentiviral particles werepurified by high-speed centrifugation and/or filtration followed byanion-exchange chromatography. The concentration of lentiviral particlescan be expressed in terms of transducing units/ml (TU/ml). Thedetermination of TU was accomplished by measuring HIV p24 levels inculture fluids (p24 protein is incorporated into lentiviral particles),measuring the number of viral DNA copies per cell by quantitative PCR,or by infecting cells and using light (if the vectors encode luciferaseor fluorescent protein markers).

As mentioned above, a 3-vector system (i.e., a 2-vector lentiviralpackaging system) was designed for the production of lentiviralparticles. A schematic of the 3-vector system is shown in FIG. 2.Briefly, and with reference to FIG. 2, the top-most vector is a helperplasmid, which, in this case, includes Rev. The vector appearing in themiddle of FIG. 2 is the envelope plasmid. The bottom-most vector is thetherapeutic vector, as described herein.

Referring more specifically to FIG. 2, the Helper plus Rev plasmidincludes a CAG enhancer (SEQ ID NO: 27); a CAG promoter (SEQ ID NO: 19);a chicken beta actin intron (SEQ ID NO: 28); a HIV gag (SEQ ID NO: 20);a HIV Pol (SEQ ID NO: 21); a HIV Int (SEQ ID NO: 22); a HIV RRE (SEQ IDNO: 23); a HIV Rev (SEQ ID NO: 24); and a rabbit beta globin poly A (SEQID NO: 29).

The Envelope plasmid includes a CMV promoter (SEQ ID NO: 25); a betaglobin intron (SEQ ID NO: 30); a VSV-G (SEQ ID NO: 28); and a rabbitbeta globin poly A (SEQ ID NO: 31).

Example 2 Development of a Lentiviral Vector that Expresses FDPS

The purpose of this Example was to develop an FDPS lentivirus vector.

Inhibitory RNA Design: The sequence of Homo sapiens Farnesyl diphosphatesynthase (FDPS) (NM_002004.3) mRNA was used to search for potentialsiRNA or shRNA candidates to knockdown FDPS levels in human cells.Potential RNA interference sequences were chosen from candidatesselected by siRNA or shRNA design programs such as from GPP Web Portalhosted by the Broad Institute(http://portals.broadinstitute.org/gpp/public/) or the BLOCK-iT RNAiDesigner from Thermo Scientific(https://rnaidesigner.thermofisher.com/rnaiexpress/). Individualselected shRNA sequences were inserted into a lentiviral vectorimmediately 3 prime to a RNA polymerase III promoter such as H1 (SEQ IDNO: 16), U6 (SEQ ID NO: 54), or 7SK (SEQ ID NO: 55) to regulate shRNAexpression. These lentivirus shRNA constructs were used to transducecells and measure the change in specific mRNA levels. The shRNA mostpotent for reducing mRNA levels were embedded individually within amicroRNA backbone to allow for expression by either the EF-1alpha or CMVRNA polymerase II promoters. The microRNA backbone was selected frommirbase.org. RNA sequences were also synthesized as synthetic siRNAoligonucleotides and introduced directly into cells without using alentiviral vector.

Vector Construction: For FDPS shRNA, oligonucleotide sequencescontaining BamHI and EcoRI restriction sites were synthesized byEurofins MWG Operon. Overlapping sense and antisense oligonucleotidesequences were mixed and annealed during cooling from 70 degrees Celsiusto room temperature. The lentiviral vector was digested with therestriction enzymes BamHI and EcoRI for one hour at 37 degrees Celsius.The digested lentiviral vector was purified by agarose gelelectrophoresis and extracted from the gel using a DNA gel extractionkit from Thermo Scientific. The DNA concentrations were determined andvector to oligo (3:1 ratio) were mixed, allowed to anneal, and ligated.The ligation reaction was performed with T4 DNA ligase for 30 minutes atroom temperature. 2.5 microliters of the ligation mix were added to 25microliters of STBL3 competent bacterial cells. Transformation wasachieved after heat-shock at 42 degrees Celsius. Bacterial cells werespread on agar plates containing ampicillin and drug-resistant colonies(indicating the presence of ampicillin-resistance plasmids) wererecovered and expanded in LB broth. To check for insertion of the oligosequences, plasmid DNA was extracted from harvested bacteria cultureswith the Thermo Scientific DNA mini prep kit. Insertion of shRNAsequences in the lentiviral vector was verified by DNA sequencing usinga specific primer for the promoter used to regulate shRNA expression.Using the following target sequences, exemplary shRNA sequences weredetermined to knock-down FDPS:

shRNA sequences were then assembled into a synthetic microRNA (miR)under control of the EF-1 alpha promoter. Briefly, a miR hairpinsequences, such as miR30, miR21, or miR185 as detailed below, wasobtained from mirbase.org. The 19-22mer shRNA target sequence was usedto construct the synthetic miR sequence. The miR sequence was arrangedas an anti-sense-target-sequence-hairpin loop sequence (specific foreach microRNA)-sense target sequence.

An exemplary AAV vector witha H1 promoter (SEQ ID NO: 16), shFDPS sequence (e.g., SEQ ID NO: 4),Left Inverted Terminal Repeat (Left ITR; SEQ ID NO: 65), and RightInverted Terminal Repeat (Right ITR; SEQ ID NO: 66) can be found in FIG.14, Panel A).

Production oPIAV particles. The AAV-FDPS shRNA plasmid was combined withthe plasmids pAAV-RC2 (Cell Biolabs) and pHelper (Cell Biolabs). ThepAAV-RC2 plasmid contains the Rep and AAV2 capsid genes and pHelpercontains the adenovirus E2A, E4, and VA genes. To produce AAV particles,these plasmids were transfected in the ratio 1:1:1 (pAAV-shFDPS:pAAV-RC2: pHelper) into 293T cells. For transfection of cells in 150 mmdishes (BD Falcon), 10 micrograms of each plasmid were added together in1 ml of DMEM. In another tube, 60 microliters of the transfectionreagent PEI (1 microgram/ml) (Polysciences) was added to 1 ml of DMEM.The two tubes were mixed together and allowed to incubate for 15minutes. Then the transfection mixture was added to cells and the cellswere collected after 3 days. The cells were lysed by freeze/thaw lysisin dry ice/isopropanol. Benzonase nuclease (Sigma) was added to the celllysate for 30 minutes at 37 degrees Celsius. Cell debris were thenpelleted by centrifugation at 4 degrees Celsius for 15 minutes at 12,000rpm. The supernatant was collected and then added to target cells.

Example 13 Decreased RAP1 Prenylation in the Cells Transduced withLV-shFDPS and Treated with Zoledronic Acid

This Example illustrates that lentiviral-delivered shRNA targeting thehuman farnesyl diphosphate synthase (FDPS) gene and zoledronic acidsynergize to inhibit farnesyl diphosphate production.

FDPS is an enzyme in the isoprenoid synthesis pathway that catalyzes theproduction of farnesyl diphosphate. Inhibiting the enzyme activity ofFDPS by zoledronic acid or reduced protein expression by shRNA-mediatedknock-down will result in reduced farnesyl diphosphate levels.Farnesylation of cellular proteins requires farnesyl diphosphate. RAP1Ais a protein that is modified by farnesylation, which can be used as abiomarker for levels of cellular farnesyl diphosphate. An antibody thatspecifically recognizes reduced RAP1A farnesylation was used to measureFDPS activity after transduction with LV-shFDPS alone or in combinationwith zoledronic acid. HepG2 human hepatocellular carcinoma cells wereinfected with lentiviral vectors containing FDPS shRNA sequence #4. Forthe zoledronic acid treated cells, zoledronic acid (Sigma) was added forthe last 24 hours. After 48 hours, cells were lysed with NP-40 lysisbuffer and protein was quantified with the Bio-Rad protein assayreagent. Protein samples at 50 micrograms were electrophoresed on 4-12%Bis-Tris gels (Thermo Scientific and transferred to PVDF membranes (EMDMillipore). An immunoblot was performed using an anti-FDPS (ThermoScientific), anti-RAP1A (Santa Cruz), and an anti-actin (Sigma) antibodyas a protein loading control. Antibodies were bound with HRP-conjugatedsecondary antibodies and detected with a Licor c-DiGit Blot scannerusing the Immobilon Western ECL reagent (EMD Millipore). An increase inthe RAP1A band intensity correlates with reduced farnesylation. RAP1Adefarnesylation occurred only in the cells transduced with LV-shFDPS andtreated with zoledronic acid.
